HP-11C and complex numbers Message #1 Posted by Antlab on 27 June 2013, 5:02 p.m.
Hi all.
In this period I am exploring the interesting world of the calculator emulators, in particular for my new Android phone.
It is fascinating being able to retrace decades of development with the various models.
In these days I found a nice HP-11C emulator for Android, and I am trying to discover the main differences respect to the 15C, that I know a bit better. I also downloaded the original manual, but I still have a doubt, concerning the handling of complex numbers.
I see that the 11C, as the bigger sister, has the (i) and I functions, (over the COS and TAN keys), but I did not understand their use, because it seems that it doesn't have a Commplex Mode as in the 15C.
Could you please clarify this issue?
Thanks.
